Embodiment Construction

[0018] Although the present invention can have many different forms of embodiments, preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The invention in its broad aspects is limited to the illustrated embodiments. As used herein, the term "present invention" is not intended to limit the scope of the claimed invention, but is merely a term used to discuss exemplary embodiments of the invention for explanatory purposes.

[0019] The present invention generally includes a push button lock that selectively maintains the angle of an object, such as a wrench head, relative to a handle. The push button lock is rotatable between an engaged position and a disengaged position. Button teeth provided on the button cooperatively engage handle teeth provided on the handle when the button lock is disposed in the engaged position. When the pushbutton lock is disposed in the disengaged position, the pushbutton lock i...

Abstract

A button lock selectively retains the angle of an object relative to a handle. The button lock is rotatable between an engaged position, where the angle is retained, and a disengaged position, where the object is disengaged from the handle and can pivotally move about the handle to change the angle. In the engaged position, button teeth on the button engage with handle teeth on the handle. In thedisengaged position, the button teeth disengage the handle teeth to space the button from the handle and therefore allow free movement of the handle about the button. The button therefore quickly andeasily retains the angle between the object and the handle.

Description

technical field [0001] The present invention relates generally to push button locks. More particularly, the present invention relates to push button locks for flex joint torque applying wrenches such as ratchet wrenches, breaker bars. Background technique [0002] For example, a movable head (swivel head) torque applying wrench (eg, a ratchet or socket wrench) is a common tool used to secure workpieces in hard-to-reach places. The swivel head allows the head of the wrench to pivot about the swivel joint and selectively remain on the handle. The user can thus operate the ratchet wrench at a desired angle between the head of the wrench and the handle to allow easier access to the workpiece. [0003] Existing movable head ratchet wrenches include various movable joints. For example, some existing wrenches incorporate a locking button into the handle of the tool. Other designs are difficult to manufacture, or allow dirt to get in and jam the button lock. Contents of the in...
